This is my .java file in src:
package com.wao.texttime;
import java.util.Calendar;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class TextTime extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView textView = (TextView) findViewById(R.id.TextView01);
Calendar cal = Calendar.getInstance();
cal.setTimeInMillis(System.currentTimeMillis());
cal.set(Calendar.HOUR_OF_DAY, 6);
cal.set(Calendar.MINUTE, 15);
cal.set(Calendar.SECOND, 0);
long vask_1 = cal.getTimeInMillis();
cal.set(Calendar.HOUR_OF_DAY, 10);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
long vask_2 = cal.getTimeInMillis();
cal.set(Calendar.HOUR_OF_DAY, 14);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
long vask_3 = cal.getTimeInMillis();
cal.set(Calendar.HOUR_OF_DAY, 16);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
long vask_4 = cal.getTimeInMillis();
cal.set(Calendar.HOUR_OF_DAY, 19);
cal.set(Calendar.MINUTE, 0);
cal.set(Calendar.SECOND, 0);
long vask_5 = cal.getTimeInMillis();
long now = System.currentTimeMillis();
if(now > vask_1 && now < vask_2)
{
textView.setText("5");
}
else if(now > vask_2 && now < vask_3)
{
textView.setText("1");
}
else if(now > vask_3 && now < vask_4)
{
textView.s开发者_运维知识库etText("2");
}
else if(now > vask_4 && now < vask_5)
{
textView.setText("3");
}
}
}
I've been told I can use the OnResume to reload the current time to update the text in the TextView. But, I don't know how to use it in the file. Do you have any suggestions?
After the closing }
of your onCreate
method, add this:
@Override
protected void onResume(){
super.onResume();
// code to update the date here
}
You will also have to move the declarations of your TextView
outside the onCreate
method, or at least you will probably want to. To do this, add a line like this before the onCreate
method:
private TextView textView;
and then in your onCreate
you just need this:
textView = (TextView) findViewById(R.id.TextView01);
Then you can access textView
from your onResume
method too.
Hope that helps.
